The 1.4-GW Sofia offshore wind farm will be located on Dogger Bank in the central North Sea, 195 km (121 mi) off the UK’s northeast coast.
The contract is valued at more than €200 million ($235 million). The companies signed the preferred bidder agreement in November 2020.
Prysmian Group will be responsible for the design, supply, installation, and commissioning of an HVDC symmetrical monopole cable system that will connect Sofia’s offshore converter station with the onshore converter station in Teesside. The project involves more than 440 km (273 mi) of ±320 kV submarine export cables with XLPE insulation, and 15 km (9.3 mi) of ±320 kV land cables with P-Laser insulation.
The company’s new cable laying vessel Leonardo da Vinci will perform the offshore cable operations. Commissioning of the project is scheduled by the end of 2026.
